The Hura-Mafa River's mouth is located in the southern coast of Naho Bay. The river flows south from there, flanked by rocky cliff-faces. The Hura-Mafa acts as somewhat of a border between Ko-Wahi and Ga-Wahi, though it does flow between and terminate amongst Ko-Wahi's snow-covered mountains.
The Hura-Mafa is a popular area for settlers - many small encampments line the banks of the river. A small port at the terminus of the river connects with Sky's Heights Way, and Ga-Koro lies near the river's mouth.
The cliff faces/mountainsides often found on either side of the river are usually capped with greenery while closer to Naho Bay, or snow and ice while within Ko-Wahi.
